Description

Technical Field

[0001] This application relates to the field of material shearing and processing, and in particular to a shearing structure. Background Technology

[0002] A metal slitting machine is a common metal processing equipment, typically used to longitudinally cut wide metal coils into several narrower strips, which are then rewound into smaller coils. A slitting machine usually includes a conveying assembly and a shearing structure. The conveying assembly transports the coil, and the shearing structure cuts the wide coil as it passes through.

[0003] The shearing structure typically includes a disc cutter and a grooved roller. When a wide strip of material passes between the disc cutter and the grooved roller, the disc cutter and the grooved roller work together to slit the wide strip. In the slitting of aluminum foil, the disc cutter is in prolonged contact and friction with the aluminum foil, causing the blade edge to heat up. After prolonged operation, this can easily lead to wear and tear on the blade edge. Simultaneously, aluminum foil cutting generates aluminum foil debris, which falls onto the aluminum foil surface. When the aluminum foil is used in batteries, there is a risk of puncturing the battery separator.

[0004] In the prior art, in order to reduce aluminum foil debris generated during aluminum foil cutting, Chinese patent CN118893660B discloses an aluminum foil cutting device for the production of aluminum electrolytic capacitors, which includes a rectangular block with a blower groove and a suction groove. In this technical solution, the dust on the disc cutter is blown up by the blower groove and sucked away by the suction groove, thus achieving dust cleaning.

[0005] However, in the above solution, when the aluminum foil flows through the blade at high speed, the edge of the aluminum foil and the side of the blade generate intense friction. Under the action of pressure and the instantaneous heat generated by friction, tiny aluminum shavings soften and firmly adhere to the disc cutter, making it difficult for the airflow to blow them off. As the disc cutter is used for a longer period of time, the deposits gradually accumulate on the disc cutter, changing the shearing gap between the disc cutter and the groove roller, thus making burrs more likely to appear at the shearing point and affecting the shearing quality of the strip. Summary of the Invention

[0006] To reduce the possibility that deposits on the disc cutter may affect the shearing quality of the strip, this application provides a shearing structure.

[0007] This application provides a shearing structure, which adopts the following technical solution: A shearing structure includes a base frame, a slitting mechanism, a cleaning mechanism, and a self-cleaning mechanism; the slitting mechanism includes a slitting drive assembly and a plurality of disc blades, the slitting drive assembly is disposed on the base frame, the disc blades are disposed on the slitting drive assembly, and the slitting drive assembly is used to drive the disc blades to translate and rotate; the disc blades cooperate with the grooved rollers to shear the strip material; The cleaning mechanism includes a support base, a cleaning assembly, and a suction assembly. The support base is disposed on the slitting drive assembly, and a ventilation cavity is formed inside the support base. The cleaning assembly includes a cleaning drive component and a cleaning plate. The cleaning drive component is disposed in the ventilation cavity, and the cleaning plate is disposed on the cleaning drive component. The cleaning drive component is used to drive the cleaning plate to move closer to or away from the disc cutter. The disc blade abuts against and rotates with the cleaning plate, causing the cleaning plate to clean the surface of the disc blade; the suction assembly is disposed on the support base and is used to suck up the adhering material scraped off by the cleaning plate; The self-cleaning mechanism is disposed in the ventilation cavity. When the cleaning plate is located in the ventilation cavity, the suction component generates airflow in the ventilation cavity and drives the self-cleaning mechanism to clean the cleaning plate.

[0008] By adopting the above technical solution, when stubborn aluminum foil debris accumulates on the surface of the disc cutter due to frictional heat or electrostatic adsorption during long-term shearing, a cleaning drive unit drives a cleaning plate to extend from the support base and abut against the rotating disc cutter, scraping off the deposits. Simultaneously, the suction component promptly removes the scraped debris, reducing the possibility of secondary re-entrainment and thus minimizing the likelihood of deposits falling onto the strip or cutter rollers and affecting strip production quality.

[0009] In addition, after the cleaning plate finishes cleaning and returns to the ventilation cavity, the suction component generates airflow in the ventilation cavity, which drives the self-cleaning mechanism to clean the cleaning plate, improving the cleanliness of the cleaning plate and the reliability of the cleaning plate for the disc cutter.

[0010] Optionally, the slitting drive assembly includes a first translation drive, a plurality of second translation drives, and a plurality of rotation drives; the first translation drive is mounted on the base frame, the second translation drives are mounted on the first translation drive, the rotation drives are mounted on the second translation drives, and the disc cutter is mounted on the rotation drive; the first translation drive is used to drive the second translation drives to move on the base frame; the second translation drives are used to drive the disc cutter to move toward or away from the base frame; and the rotation drives are used to drive the disc cutter to rotate.

[0011] By adopting the above technical solution, the first translation drive component enables the movement of multiple disc cutters on the base frame, thereby flexibly adjusting the spacing between adjacent disc cutters to meet the slitting requirements of strips of different widths. The second translation drive component can adjust the position of the disc cutters, thereby adjusting the cutting depth of the disc cutters to meet the slitting requirements of strips of different thicknesses.

[0012] Optionally, it also includes an angle adjustment mechanism, which includes a flipping drive and a flipping bracket. The flipping bracket is rotatably mounted on the base frame, and the flipping drive is mounted on the base frame. The flipping drive is used to drive the flipping bracket to rotate on the base frame. The first translation drive is connected to the flipping bracket.

[0013] By adopting the above technical solution, the rotation of the flip bracket allows the disc cutter to adjust the cutting angle, thereby enabling the disc cutter to adapt to strips of different thicknesses in conjunction with the second driving component.

[0014] Optionally, a suction tube is also included, which is disposed on the base frame and is used to remove debris from the strip.

[0015] By adopting the above technical solution, the suction tube can remove most of the flying debris and dust generated during the shearing process, reducing the possibility of aluminum foil debris falling directly onto the strip surface and causing indentations and scratches.

[0016] Optionally, the suction assembly includes a suction member and a suction drive member. The suction drive member is disposed on the support base, and the suction member is disposed on the suction drive member. The suction drive member is used to drive the suction member to move closer to or away from the disc cutter. The suction member has an air intake port. When the cleaning plate abuts against the disc cutter, the suction drive member drives the air intake port to move closer to the cleaning plate.

[0017] By adopting the above technical solution, when the cleaning plate cleans the disc cutter, the suction drive actively moves the air intake to a position close to the cleaning plate, thereby shortening the distance between the negative pressure source and the debris, so that the airflow can directly suck away the scraped heavy or clump debris, reducing the possibility of debris scattering.

[0018] Optionally, the self-cleaning mechanism includes a sealing plate and a cleaning cylinder; the sealing plate is disposed on the suction member, and the support base has a through hole and an air inlet communicating with the ventilation cavity; the through hole is used for the sealing plate to pass through; the cleaning cylinder is rotatably disposed in the ventilation cavity; The cleaning plate is located inside the ventilation cavity, and when the sealing plate blocks the through hole, the suction member is connected to the ventilation cavity, so that the air inlet draws in air and drives the cleaning cylinder to clean the cleaning plate.

[0019] By adopting the above technical solution, when the cleaning plate returns to the ventilation chamber and the sealing plate blocks the through hole, the air intake is connected to the ventilation chamber, allowing external airflow to enter the ventilation chamber from the air intake. After the airflow enters the ventilation chamber, it drives the cleaning cylinder to automatically clean the cleaning plate, improving the cleanliness of the cleaning plate.

[0020] Optionally, the cleaning cylinder includes a cylinder body, fan blades, and a brush; the cylinder body is rotatably disposed within the ventilation cavity, the fan blades are disposed on the cylinder body, and the brush is disposed on the cylinder body; when the airflow in the ventilation cavity flows through the cylinder body, the fan blades drive the brush to clean the cleaning plate.

[0021] By adopting the above technical solution, when the airflow in the ventilation cavity flows through the cleaning cylinder, the fan blades drive the cylinder to rotate, thereby causing the brush on the outer wall of the cylinder to clean the cleaning plate, thus improving the cleanliness of the cleaning plate.

[0022] Optionally, the support base is provided with an air inlet for blowing air onto the disc cutter.

[0023] By adopting the above technical solution, the airflow from the blower can blow up loosely attached aluminum foil debris from the surface of the disc cutter, causing it to detach from the cutter surface, and then be sucked away by the external suction component, further improving the cleanliness of the disc cutter.

[0024] Optionally, the cleaning drive component includes a mounting base, a connecting frame, and an elastic element; the mounting base is disposed within the ventilation cavity, the connecting frame is slidably connected to the mounting base, the elastic element is located between the mounting base and the connecting frame, and the cleaning plate is connected to the connecting frame; the mounting base communicates with the air outlet. When the air inlet is closed, the mounting base is ventilated, causing the cleaning plate to move toward the disc cutter.

[0025] By adopting the above technical solution, when the air inlet is closed, the airflow from the air inlet enters the mounting base, causing the connecting frame to push the cleaning plate against the disc cutter under air pressure, thereby performing cleaning. When the air path is depressurized, the elastic element pulls the cleaning plate back into the ventilation cavity, reducing the possibility of the cleaning plate interfering with the operation of the disc cutter.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By incorporating a cleaning mechanism, when stubborn aluminum foil debris accumulates on the surface of the disc cutter due to frictional heat or electrostatic adsorption during long-term shearing, a cleaning drive unit extends the cleaning plate from the support base and contacts the rotating disc cutter, scraping away the debris. Simultaneously, the suction component promptly removes the scraped debris, reducing the possibility of secondary re-entrainment and thus minimizing the likelihood of debris falling onto the strip or cutter rollers and affecting strip production quality. Furthermore, after the cleaning plate completes cleaning and returns to the ventilation chamber, the suction component generates airflow within the ventilation chamber, which in turn drives the self-cleaning mechanism to clean the cleaning plate, improving its cleanliness and reliability in cleaning the disc cutter. 2. By setting up a slitting drive assembly, the first translation drive component enables the movement of multiple disc cutters on the base frame, thereby flexibly adjusting the spacing between adjacent disc cutters to adapt to the slitting requirements of strips of different widths. The second translation drive component can adjust the position of the disc cutters, thereby adjusting the cutting depth of the disc cutters to adapt to slitting work of strips of different thicknesses; 3. By incorporating a self-cleaning mechanism, when the cleaning plate returns to the ventilation chamber and the sealing plate blocks the through-hole, the air intake connects with the ventilation chamber, allowing external airflow to enter the ventilation chamber through the air intake. After entering the ventilation chamber, the airflow drives the cleaning cylinder to automatically clean the cleaning plate, improving the cleanliness of the cleaning plate.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 This application will be described in further detail.

[0030] Example 1 Embodiment 1 of this application discloses a shearing structure, such as Figure 1 The shearing structure includes a base frame 1, a cutting mechanism 2, an angle adjustment mechanism 5, and a suction tube 6.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, the slitting mechanism 2 includes a slitting drive assembly 21, multiple disc cutters 22, and grooved rollers 23. The grooved rollers 23 are rotatably mounted on the base frame 1 via a motor. The angle adjustment mechanism 5 includes a tilting drive component 51 and a tilting bracket 52. The tilting bracket 52 is rotatably mounted on the base frame 1, and the body of the tilting drive component 51 is fixedly mounted on the base frame 1. The output end of the tilting drive component 51 is fixedly connected to the tilting bracket 52. The tilting drive component 51 can drive the tilting bracket 52 to rotate on the base frame 1. Preferably, the tilting drive component 51 is a motor.

[0032] Among them, such as Figure 2As shown, the slitting drive assembly 21 includes a first translation drive 211, a second translation drive 212, and a rotation drive 213. The body of the first translation drive 211 is fixedly mounted on the flipping bracket 52. In this embodiment, the first translation drive 211 has multiple output ends, which can move independently. Preferably, the first translation drive 211 is a linear module. The body of the second translation drive 212 is fixedly connected to the output ends of the first translation drive 211, and the output ends of the second translation drive 212 are fixedly connected to the body of the rotation drive 213. The output ends of the rotation drive 213 are fixedly connected to the disc cutter 22. The rotation drive 213 can drive the disc cutter 22 to rotate, thereby cooperating with the slotted roller 23 to cut the strip. Preferably, the second translation drive 212 is a linear module, and the rotation drive 213 is a motor.

[0033] This application utilizes a first translation drive 211 to allow multiple disc cutters 22 to translate independently on the base frame 1, thereby adjusting the distance between adjacent disc cutters 22 and meeting the slitting requirements of strips with different widths. A flip drive 51 drives a flip bracket 52 to rotate directly, adjusting the cutting angle of the disc cutters 22. A second translation drive 212 allows the disc cutters 22 to move perpendicular to the length of the slot roller 23, adjusting their cutting position. Through the cooperation of the second translation drive 212 and the angle adjustment mechanism 5, the shearing structure of this application can be applied to shearing strips of different thicknesses, improving the applicability of the slitting machine.

[0034] like Figure 1 As shown, the suction pipe 6 is fixedly installed on the base frame 1. The suction pipe 6 is connected to an external air passage, so that when the disc cutter 22 cuts the aluminum foil strip, it sucks away the debris generated during the cutting process, reducing the possibility of aluminum foil debris falling onto the surface of the strip and affecting the production quality.

[0035] The implementation principle of a shear structure in Embodiment 1 of this application is as follows: When slitting aluminum foil strip, the position of the disc cutter 22 is adjusted by the slitting drive assembly 21 and the angle adjustment mechanism 5 according to production needs. When the wide strip enters between the disc cutter 22 and the groove roller 23, the disc cutter 22 slits the strip.

[0036] Example 2 The difference between Embodiment 2 and Embodiment 1 of this application is as follows: like Figure 3 , Figure 4 and Figure 5As shown, the shearing structure also includes a cleaning mechanism 3 and a self-cleaning mechanism 4. The cleaning mechanism 3 includes a support base 31, a cleaning component 32, and a suction component 33; the self-cleaning mechanism 4 includes a sealing plate 41 and a cleaning cylinder 42.

[0037] Specifically, such as Figure 4 and Figure 6 As shown, the support base 31 is fixedly installed on the output end of the second translation drive 212, and the disc cutter 22 is located inside the support base 31. A ventilation cavity 311 is provided inside the support base 31. A through hole 312 and an air inlet 313 are provided on the side of the support base 31 near the disc cutter 22. The through hole 312 and the air inlet 313 are respectively connected to the ventilation cavity 311, and the air inlet 313 is located below the through hole 312.

[0038] like Figure 5 As shown, the suction assembly 33 includes a suction member 331 and a suction drive member 332. The body of the suction drive member 332 is fixedly connected to the support base 31, and the output end of the suction drive member 332 is fixedly connected to the suction member 331. The suction member 331 is slidably connected to the support base 31 in a sealed manner. An air intake port 3311 is provided on the suction member 331, and an external air source is connected to the suction member 331. The suction drive member 332 can drive the suction member 331 to slide on the support base 31, thereby allowing the air intake port 3311 to pass through the support base 31 or communicate with the ventilation cavity 311.

[0039] In addition, such as Figure 6 and Figure 7 As shown, the support base 31 is also provided with an air inlet 314, which is connected to the air channel 315. The air channel 315 is connected to an external air source, so that the air inlet 314 can blow air outward.

[0040] like Figure 5 and Figure 7 As shown, the cleaning assembly 32 includes a cleaning drive component 321 and a cleaning plate 322. The cleaning drive component 321 includes a mounting base 3211, a connecting frame 3212, and an elastic element 3213. Specifically, the mounting base 3211 is fixedly installed inside the ventilation cavity 311, the connecting frame 3212 is slidably connected to the mounting base 3211, one end of the elastic element 3213 is fixedly connected to the connecting frame 3212, and the other end is fixedly connected to the mounting base 3211. The connecting frame 3212 is fixedly connected to the cleaning plate 322. Preferably, the elastic element 3213 is a spring. The cleaning plate 322 is located near the through hole 312, and the mounting base 3211 communicates with the air duct 315.

[0041] like Figure 5 , Figure 8 and Figure 9As shown, the self-cleaning mechanism 4 includes a sealing plate 41 and a cleaning cylinder 42. The cleaning cylinder 42 includes a cylinder body 421 and fan blades 422. The cylinder body 421 is hollow, allowing airflow to pass through its interior. A fan blade 422 is fixedly installed at each end of the cylinder body 421. A support frame 7 is fixedly connected inside the ventilation cavity 311, and the fan blades 422 are rotatably connected to the support frame 7, allowing them to rotate within the ventilation cavity 311. A brush is installed on the outer wall of the cylinder body 421, and the sealing plate 41 is fixedly installed on the suction member 331.

[0042] It should be noted that when the disc cutter 22 cuts the aluminum foil strip, there is a possibility that the aluminum foil debris generated during the cutting process may adhere to the disc cutter 22. The adhered aluminum foil debris will increase the thickness of the disc cutter 22. At the same time, it is easy to fall off during the slitting process, thus affecting the production quality of slitting.

[0043] During the slitting process, the shearing structure of this application drives the suction member 331 to move, positioning the suction port 3311 within the ventilation chamber 311. At this time, the sealing plate 41 blocks the through hole 312, and simultaneously, the blower 314 blows air to dislodge loosely attached aluminum foil debris from the disc cutter 22. Because the sealing plate 41 blocks the through hole 312, when the external air passage connected to the suction member 331 draws air, the airflow outside the support base 31 passes sequentially through the air inlet 313, the ventilation chamber 311, and the suction port 3311. This causes the aluminum foil debris blown up by the blower 314 to pass sequentially through the air inlet 313, the ventilation chamber 311, and the suction port 3311 before being discharged, reducing the possibility of aluminum foil debris falling onto the strip.

[0044] Furthermore, due to the instantaneous high temperature generated during the shearing process of the disc cutter 22, some aluminum foil debris softens and adheres firmly to the disc cutter 22. At this time, the airflow from the blower 314 is not easily blown off. As the disc cutter 22 is used for a longer period of time, aluminum foil debris gradually accumulates on the disc cutter 22, increasing the thickness of the disc cutter 22 and affecting the shearing quality of the strip.

[0045] In this application, after each batch of strip is slit, the suction drive 332 drives the suction member 331 to move closer to the disc cutter 22, causing the sealing plate 41 to open the through hole 312 and block the air outlet 314. At this time, the airflow from the external air source connected to the air channel 315 enters the mounting base 3211, causing the connecting frame 3212 to overcome the elastic force of the elastic member 3213 under the action of air pressure, and driving the cleaning plate 322 to move closer to the disc cutter 22. When the cleaning plate 322 moves to abut against the disc cutter 22, the disc cutter 22 rotates at a low speed, causing the cleaning plate 322 to scrape off the deposits on the disc cutter 22. During this time, the suction member 331 moves to a position where the suction port 3311 is close to the cleaning plate 322, thereby shortening the distance between the suction port 3311 and the aluminum foil debris, and improving the reliability of sucking away the scraped aluminum foil debris. In Embodiment 2 of this application, when the air outlet 314 is unobstructed, the airflow is preferentially discharged from the air outlet 314. At this time, the air pressure inside the mounting base 3211 is low and insufficient to overcome the elastic force of the elastic element 3213.

[0046] After the cleaning plate 322 finishes cleaning the disc cutter 22, the external air passage connected to the mounting base 3211 exhausts the air, causing the cleaning plate 322 to return to the ventilation cavity 311 under the elastic force of the elastic member 3213. Then, the suction drive member 332 drives the suction member 331 to move away from the disc cutter 22, and connects the suction port 3311 with the ventilation cavity 311. At the same time, the sealing plate 41 moves to block the through hole 312 and opens the blower vent 314, so that the next batch of cutting work can be carried out.

[0047] When the through hole 312 is blocked, the cleaning plate 322 returns to the ventilation chamber 311. At this time, the cleaning plate 322 is within the cleaning range of the brush on the cleaning cylinder 42. As the airflow flows through the air inlet 313, the ventilation chamber 311 and the air intake 3311 in sequence, the airflow passes through the inner side of the cylinder 421 and drives the cylinder 421 to rotate through the fan blade 422. This causes the brush to rotate and sweep the aluminum foil debris scraped on the cleaning plate 322, thereby cleaning the cleaning plate 322 and causing the aluminum foil debris swept by the cleaning plate 322 to be discharged with the airflow.

[0048] The implementation principle of a shearing structure in Embodiment 2 of this application is as follows: During the slitting process, the suction port 3311 of the suction unit 331 is located inside the ventilation chamber 311, the through hole 312 is blocked by the sealing plate 41, and both the blower port 314 and the air inlet 313 are open. At this time, air is blown through the air passage connected to the blower channel 315, and air is drawn in through the air passage connected to the suction unit 331. This causes the loosely attached aluminum foil debris on the disc cutter 22 to be blown up and then sucked away after passing through the air inlet 313, the ventilation chamber 311, and the suction port 3311 in sequence.

[0049] After the slitting process is completed, the suction drive 332 drives the suction component 331 to move closer to the disc cutter 22. When the suction port 3311 is close to the disc cutter 22, the sealing plate 41 opens the through hole 312, and at the same time, the air outlet 314 is blocked. At this time, the air passage connected to the mounting base 3211 is ventilated, causing the connecting frame 3212 to drive the cleaning plate 322 to abut against the disc cutter 22. After the cleaning plate 322 abuts against the disc cutter 22, the disc cutter 22 rotates at a low speed, thereby causing the cleaning plate 322 to scrape off the firmly adhered aluminum foil debris. Furthermore, since the suction port 3311 is close to the cleaning plate 322 at this time, the aluminum foil debris scraped off by the cleaning plate 322 is directly sucked away by the suction port 3311.

[0050] After the cleaning plate 322 cleans the disc cutter 22, the air passage connected to the mounting base 3211 is de-aired, causing the cleaning plate 322 to return to the ventilation cavity 311 under the action of the elastic element 3213. After the cleaning plate 322 returns to the ventilation cavity 311, the suction drive 332 drives the suction element 331 to move away from the disc cutter 22, and connects the suction port 3311 to the ventilation cavity 311, facilitating the slitting of the next batch of roll material.

[0051] During the slitting of the next batch of roll material, airflow enters the ventilation chamber 311 through the air inlet 313. As the airflow passes through the ventilation chamber 311, it drives the cylinder 421 to rotate via the fan blades 422, thereby actuating the brush cleaning plate 322. The aluminum foil debris swept off the cleaning plate 322 by the brush is sucked away by the airflow through the suction port 3311, thus improving the cleanliness of the cleaning plate 322 and ensuring the cleaning effect of the cleaning plate 322 on the disc cutter 22.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
